ADN4604 Terminations

I am looking to connect the High Speed inputs of an ADN4604 directly to an Equaliser's Output. I have the option of 100ohm parallel termination or 50ohm termination to VCC at the ADN4604 input. What would be your preferred choice for a short route?

Also, I need to AC couple the High Speed output of the ADN4604. The downline device is 2.5V. Do I need to connect the VTTOx supplies? I'm guessing not. Do I just need to enable the parallel 50ohm terminations to give me 100ohms and leave the VTTOx connection O\C? Could you confirm this for me please.

Thanks. Regards, Rob.
